Company: Zoox
Role: Backend Engineer
Category: System Design
Difficulty: hard
Interview Round: Onsite
Design a large-scale ride-hailing system similar to Uber.
The system should support:
- riders creating ride requests with pickup and destination
- drivers going online or offline and continuously updating their location
- matching riders with nearby available drivers
- managing driver, rider, and trip state in real time
- dispatching rides at high scale across many regions
Discuss the functional and non-functional requirements, API design, data model, service architecture, ride-matching flow, location update pipeline, scalability strategy, and how you would handle consistency, failures, and stale data.
Quick Answer: This question evaluates competency in designing large-scale, real-time distributed systems, including distributed architecture, geo-spatial indexing and matching, real-time state management, API and data modeling, scalability strategies, consistency models, and fault tolerance.
